Help for my 12 year old daughter!

My 12 year old daughter wants to try and play the game, but without brake assist, as this auto routine dictates the speed of the car on the green/orange/red arrows of the racing line, but if she tries to drive round a corner inside the racing line, the auto keeps the car very slow and everything drives past her.

Can I set up a profile for her as well, so that she cannot affect my save-games?

The game is played through STEAM, so where would the alterations/mods go?
